Product Features:

1. The material feeding system incorporates a CNC-controlled clamping carriage driven by high-performance servo motors, ensuring rapid workpiece transportation together with exceptional positioning accuracy and repeatability throughout the entire machining process.

2. Three high-speed BT40 precision spindle units are arranged to simultaneously machine all three surfaces of H-beam sections. Supporting carbide drilling with through-spindle coolant and spindle speeds of up to 3,000 rpm, the system delivers superior drilling performance, outstanding hole quality, and efficient chip evacuation through an integrated chain-type chip conveyor.

3. The equipment is equipped with an advanced Minimum Quantity Lubrication (MQL) system that supports both internal and external coolant delivery. Each spindle assembly features an independent external coolant nozzle and an internal coolant channel, allowing operators to select internal cooling, external cooling, or a combined cooling mode according to specific machining requirements.

4. An optional Automatic Tool Changer (ATC) is available to perform fully automatic tool replacement without manual intervention. This feature significantly shortens tool change time, minimizes machine idle periods, and enhances overall production efficiency.

5. An optional hydraulic CNC rotary disc marking system can be integrated into the machine. Driven by a high-precision servo motor, the marking disc automatically indexes among 36 selectable characters, providing fast, accurate, and highly repeatable identification marking for structural steel components.

6. Integrated automatic scribing and tapping functions eliminate the need for conventional manual layout procedures. The scribing unit accurately produces welding reference lines on both the flanges and webs of H-beams, while the tapping function directly machines threaded holes in structural members, improving machining accuracy, reducing manual labor, and increasing manufacturing productivity.

7. Throughout material feeding and machining operations, workpiece lifting, lateral positioning, clamping, locking, and release are all hydraulically controlled. This fully hydraulic workholding system ensures secure material fixation, excellent machining stability, and dependable performance during continuous production.

8. The control platform integrates an industrial computer with a PLC-based CNC system utilizing premium components supplied by internationally recognized manufacturers. Multiple programming methods are supported, while machining data generated from AutoCAD, TEKLA Structures, DXF, and DSTV files can be imported directly, simplifying programming procedures and improving production management efficiency.

The demonstration workpieces include standard H-beam specimens with various flange widths and web thicknesses, together with channel steel samples of different specifications, providing a comprehensive display of the machine's machining performance. These representative samples clearly demonstrate precise hole positioning, high-quality threaded holes, and sharp, well-defined marking results, allowing customers, engineers, and quality inspectors to accurately evaluate the equipment's machining precision, processing consistency, and overall production reliability under practical operating conditions.

The High-Speed CNC H-Beam Drilling, Marking, and Tapping Machine is extensively applied in structural steel fabrication plants, bridge engineering, and other heavy steel construction industries. Within steel fabrication facilities, the equipment performs high-precision drilling, tapping, marking, and scribing on H-beams used for structural frames, columns, and support systems, supplying accurately machined components for efficient assembly and dependable structural performance. In bridge construction projects, it provides precision machining of H-beam members, improving connection accuracy, structural integrity, and long-term load-bearing performance. By combining high machining efficiency, outstanding precision, and reliable operational stability, the machine delivers an ideal manufacturing solution for modern steel structure production and large-scale infrastructure construction.
